fix(playground): resolve auto group model listing (#6163)

* fix(playground): resolve auto group model listing

- merge and deduplicate available models in configured auto group order.
- reuse special usable group rules and add model filtering regression coverage.

* refactor: extract GetGroupsEnabledModels to dedupe group model expansion
